Have named changed for this as don't want school to be easily identified...
Today my two DDs aged 12 and 16, have come home discussing a school assembly they had this morning. This was a "house" assembley so pupils from all year groups (7 to 13) and all ability ranges were in attendance and it was about the white ribbon campaign against domestic violence. DD1 has described it as containing a powerpoint presentation with very emotive music "everybody hurts" accompanying pictures of bruised and battered female victims of domestic violence, and lots of slides giving stats about sexual assault and rape.
Now I do not object to the campaign in anyway, and I think it is a very worthy cause to raise awareness of. However, this is a catholic school, where my daughter who is in Y12 (lower 6th) has never received any sex education at all except that
- she was told the biological facts in science
- at the end of year 9 a Christian charity spoke to them about abstinence.
She has never been given any information at all about contraception, or the emotional aspects of a sexual relationship - luckily dh and I have discussed this with them at home but I know other parents won't have. I have accepted the lack of sex education as in every other respect it is an excellent school, and they argue that to promote contraception etc would be to undermine their Catholic principles 
I just feel that an assembly about domestic violence where the pupils have had absolutely no contextual information about a positive, healthy sexual relationship, is likely to leave students, particularly girls, feeling scared about sex, rather than empowered - from speaking to dd2, it is apparent that she found some of the images quite upsetting.
AIBU? and how do I articulate my concerns to the school?
